LRH ballistic calculator

Can someone tell me why the LRH ballistic calculator does not use the NP-R1 reticle for the MOA version?
The reticle that is on the program is a 14 power MOA reticle.
I don't even know a scope that comes with that reticle on it?
It would seem more useful to use a version of an MOA reticle that is more common for the program.
